I was prescribed 50 mg of clomid to take cd 2-6 and 2000mg of metformin (that I had to increase over 4weeks) this was for pcos too.
I was prescribed it at the end of october and by the end of november I was pregnant!!! So it happened for me on the first month!
While I was researching them, it said if you were on both medications you had a very high chance of ovulating!! So keep positive!
I wish you all the best and I hope things work as well for you as they have for me. Please keep me posted on how you get on
